• Based on the dust sensor, it works well in detecting very fine particles, such as cigarette smoke, it is a commonly used air purifier system.
• Contains IR LED and photoelectric transistor
• By organizing them with cross angles, it is possible to detect the reflected light of dust in the air.
• has an extremely low power consumption (maximum at 20 mA, typical at 11 mA) and can be equipped with sensors up to 7 V DC
• The analog voltage is proportional to the measured concentration of dust and the sensitivity is 0.5 V / 0.1 mg / m3

Product description

Description: Pm2.5 Air Particle Monitor to detect PM2.5 levels around you and take appropriate precautions if necessary. This Pm2.5 sensor module based on optics works well in detecting very fine particles, such as cigarette smoke, and is a commonly used air purifier system. This device contains IR LEDs and a photoelectric transistor. By arranging them at cross angles, it is possible to detect the reflected light of dust in the air. It has an extremely low power consumption (maximum at 20 mA, typical at 11 mA) and can be equipped with sensors up to 7 V DC. The analog voltage is proportional to the measured dust concentration and the sensitivity is 0.5 V / 0.1 mg / m3. Specification: Power supply voltage: 5-7 V. Operating temperature: -10-65 ℃. Current consumption: max 20 mA. Minimum particle detection value: 0.8μ. Sensitivity: 0.5V / (0.1mg / m3). Cleaning air voltage: 0.9 V (typical). Storage temperature: -20 ~ 80 ℃. Lifespan: 5 years. Dimensions: 62 millimeters × 32 millimeters × 20 millimeters. The package includes: 1 X wiring 2.0mm-6P, 1 resistor 150 ohm 1 / 4W, 1 electrolytic capacitor X 220uF.
